Did you do anything to bypass the immobilizer? It could be that or something wrong with the tach wire.

This is from the troubleshooting section of the install manual. Hope it helps. The vehicle will start, but will only run for 10 seconds. Is the remote start programmed for voltage sense? Try programming the unit for low voltage reference. If this does not work, a tach wire should be used. Check diagonostics.

Try remote starting with a key in the ignition in the off position.

i bypassed the system with a boa bypass module, programmed key inside and i have also tried with the key in the ignition. I got the tach wire off of the instrument panel, the haynes said it was the tach wire but ill try some where else, what type of signal will i be looking for from the tach, thanx for helping, very quick responses hey smoke signal is that an actual website where did u get that from

the tach wire should read around 6-7 volts AC and increase with RPM.

Do a search for your model number + install or installation on this site. You may have to play around with the exact phrase.
